Nine climbers are dead after an avalanche on one of Nepal’s tallest mountains, the Guardian reports. At least five climbers were injured and have been evacuated to Kathmandu.

The avalanche hit the climbers’ camps at 7,000 meters (22,966 feet) on Mount Manaslu, a 8,163-meter (26,781-foot) peak and the eighth tallest in the world. More than 200 climbers and guides were on the mountain, but not all were in the area of the avalanche. The nationalities of only three of the dead are known at this time – German Spanish, and Nepali. The Toronto Star reports that seven climbers are missing – five French, a Canadian, and an Italian climber.

Mountain rescue crews, assisted by helicopters, are searching the area for bodies and survivors.

This is the beginning of the autumn mountaineering season in Nepal, a time right after the monsoon season when unstable weather makes avalanches more common.

This sobering news reminds me of my own trip to the Annapurna Base Camp, when a Japanese team lost some men in an avalanche on a nearby peak. It’s good to remember that adventure travel carries with it certain inherent risks.
